1. Wärmetauscher, insbesondere als Heizgaszug für einen Brennwert-Heizkessel, bestehend aus mehreren Rohren mit unterschiedlichen Längen und mit Einformungen zum Verbessern des Wärmeübergangs zwischen den Heizgasen und dem Kesselwasser, insbesondere mit einer oberen, horizontal angeordneten Brennkammer und einem darunter angeordneten Rohrbündel-Wärmetauscher, dessen einzelne Rohre über Rohrbögen mit dem Boden der Brennkammer verbunden sind, dadurch gekennzeichnet, dass die Einformungen zum Verbessern des Wärmeübergangs an einzelnen Rohren (4) oder an Gruppen von Rohren (4) unterschiedlich gestaltet sind.1. heat exchanger, in particular as a heating gas flue for a condensing boiler, consisting of several pipes of different lengths and with indentations for improving the heat transfer between the heating gases and the boiler water, in particular with an upper, horizontally arranged combustion chamber and a tube bundle heat exchanger arranged underneath, whose individual pipes are connected to the bottom of the combustion chamber via pipe bends, characterized in that the indentations for improving the heat transfer on individual pipes ( 4 ) or on groups of pipes ( 4 ) are designed differently. 2. Wärmetauscher nach Anspruch 1, dadurch gekennzeichnet, dass die unterschiedlich gestalteten Einformungen an einzelnen Rohren (4) oder an Gruppen von Rohren (4) aufeinander abgestimmt sind und für eine gleichmäßige Aufteilung der Volumenströme und/oder einen gleichmäßigen Wärmeübergang sorgen.2. Heat exchanger according to claim 1, characterized in that the differently shaped indentations on individual pipes ( 4 ) or on groups of pipes ( 4 ) are coordinated with one another and ensure a uniform distribution of the volume flows and / or a uniform heat transfer. 3. Wärmetauscher nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, dass bei Verwendung von Rohrbögen mit unterschiedlichen Radien, mindestens auf Teilstücken eines Heizgaszuges, die unterschiedlichen Einformungen zur gleichmäßigen Aufteilung der Volumenströme und/oder zur Vergleichmäßigung des Wärmeübergangs an einzelnen Rohren (4) oder an Gruppen von Rohren (4) vorzugsweise im Bereich gerader Rohrbereiche angebracht sind.3. Heat exchanger according to one of claims 1 or 2, characterized in that when using pipe bends with different radii, at least on sections of a heating gas flue, the different indentations for the uniform distribution of the volume flows and / or for evening out the heat transfer on individual pipes ( 4 ) or are attached to groups of pipes ( 4 ), preferably in the area of straight pipe areas. 4. Wärmetauscher nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass die Einformungen zur gleichmäßigen Aufteilung der Volumenströme und/oder zur Vergleichmäßigung des Wärmeübergangs vorzugsweise durch ihre Gestaltung, Anzahl, Ausrichtung und Anordnungshäufigkeit variieren und dem Wärmeübergang und/oder Volumenstrom der Heizgase in den entsprechenden Zonen angepasst sind.4. Heat exchanger according to one of claims 1 to 3, characterized in that the indentations for the uniform division of the Volume flows and / or to even out the heat transfer preferably vary by their design, number, orientation and frequency of arrangement and the Heat transfer and / or volume flow of the heating gases in the corresponding zones are adjusted.
